“The national security pretext is absurd and frankly insulting to Canadians, the closest and strongest ally the United States has had,” Ms. Freeland said.
As to the biting comments made by Mr. Kudlow, she responded: “Canada does not believe that ad hominem attacks are a particularly appropriate or useful way to conduct our relations with other countries.”
She added: “We particularly refrain from ad hominem attacks when it comes to our allies.”
Ms. Freeland said she planned to continue negotiating with the Americans over trade. “We are always prepared to talk,” she said. “That’s the Canadian way — always ready to talk and always absolutely clear about standing up for Canada.”
But for now, calling the American tariffs illegal and unjustified, she reiterated Canada’s intention to impose retaliatory tariffs, starting July 1, “which is Canada Day,” she noted. “Perhaps not inappropriate.”
For Mr. Trudeau, the G-7 summit meeting has been an important test of his leadership, at home and on the global stage. On Sunday, he continued his schedule, meeting with world leaders and trying to rise above the Twitter insults from his neighbor.
He wrote on Twitter on Sunday that the agreement at Charlevoix would, among other things, strengthen “our economies,” and protect women and the environment. “That’s what matters.”
Canadian fury at Trump notwithstanding, analysts said it was difficult to overstate the damage that bad relations with him could cause to the Canadian economy. Canada relies on the United States as its only neighbor, its military ally and its largest trading partner.
